The generator is an Kohler 8EOZ 8kw generator. It autoshutdown on me during a weekend cruise and decided to troubleshoot when I got home. Did the troubleshooting. If you don't know this generator, it is a mechanical one. But there are a series of electical shutdown features from 3 different sensors....oil pressure, coolant temperature, and exhaust temperature. When an autoshutdown is triggered, it lights a series of LED lights on the backside of the control circuit panel to alert you to what is causing the shutdown. You then follow a stupid flow chart in the maintenance manual to come to your conclusion on what is causing the shutdown. In every possible scenario, it was a control board failure that was causing the shutdown. So I replaced the control board. No joy! I then figured since the separate sensors were relatively cheap, I did the shotgun approach and ordered all 3. I put on the oil pressure one and the exhaust temperature one. The water temperature one was the wrong one so still haven't replaced that one but still....No joy on the other two!!! I have my serious doubts that the water temp sensor is the culprit.
If in fact the water temp sensor is not the cause, I guess the only place to go next is the actual oil pump??? I would find a way to put a mechanical gauge onto the oil pressure sensor "tap/hole" and see if there is in fact no oil pressure. Is there a way to bypass the oil pressure sensor to allow the engine to run for longer than the 3-5 seconds it runs before shutdown?
Anyway...open to any and all suggestions/advice. I have shotgunned about $450 bucks so far in parts and am not getting a solution. It may be important to note that the 12v circuit breaker does pop/open simultaneously upon auto shutdown. I have even tried holding/forcing that breaker in to see if it related to the autoshutdown...but the generator quit anyway.
At a loss....
